An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

The described embodiments relate to systems, methods, and apparatuses for providing an adjustable amount of tension to various portions of a body of a user. The tension can be exhibited by cables that extend from the body mounted device. The cables can be routed through a pulley assembly located with cables guides of the body mounted device. A user can adjust the tension of the cables using knobs located at the ends of the cable guides. The cables can terminate at bands, which can be attached to appendages of the user during training. When the user is wearing the body mounted device, a mounting plate of the body mounted device can conform to the shoulders of the user, and a separate plate of the body mounted device can be depressed against a back side of the user.

In one embodiment a fitness device is disclosed. The fitness device may include a central handle having a body with a central aperture through the body. The device may also include a first rod removably coupled to the central handle at a first location and a second rod removably coupled to the central handle at a second location, opposite the first location. The device may also include an elastic member having a first end and a second end, the first end being coupled to the first rod and the second end being coupled to the second rod.

An exercise machine and a resistance and brake compound control structure are disclosed. The resistance and brake compound control structure includes a sleeve, a push rod, an elastic member, a compound operating member, and a pushing member. The push rod is disposed in the sleeve. The elastic member exerts a force to the push rod for giving the push rod a return elastic force. The compound operating member includes an operating portion and a screw rod. The screw rod has a pushing end extending into the sleeve. The pushing member is disposed in the sleeve in a non-rotatable manner. The pushing member has a threaded hole. The screw rod is screwed to the threaded hole. The exercise machine uses the resistance and brake compound control structure to adjust resistance and brake.

An exercise device for compression exercises is adjustable in height and in compression force. The device includes a central housing and a plurality of plungers extending from a top side. A support member is attached to the housing on a bottom side. The support member is movable longitudinally relative to the housing and plungers from a fully retracted position to a fully extended position and is lockable in a plurality of intermediate longitudinal positions to vary the height of the device. Each plunger is operatively associated with an internal bias member that biases the plunger away from the housing. Resistance force on a plunger is adjustable via changing tension of the associated bias member with an adjustment knob to finely adjust tension. An installed bias member is removable and replaceable with a different bias member to coarsely adjust tension.

In one aspect of the disclosure, a motorized Pilates reformer system may include a frame, a carriage configured to slide along the frame, springs attached to the carriage, attachment mechanisms attached to the frame, spring motors attached to the frame, a footbar rotatably attached to the frame, and a footbar motor attached to the frame. The spring motors may be configured to cause the attachment mechanisms to each alternate between attaching one of the springs to the frame and detaching the spring from the frame. The footbar motor may be configured to rotate the footbar with respect to the frame between multiple footbar positions.

A hydraulic resistance exercise apparatus is disclosed. The apparatus has a frame adjustably supporting at least one drum body. One of an arm bar and a leg bar pivotally attached to the at least one drum body. A hydraulic vane cylinder is carried in each the at least one drum body. The hydraulic vane cylinder has one or more hydraulic channels and at least one vane coupled to one of the arm bar and the leg bar, such that operation of one of the arm bar and the leg bar urges a hydraulic fluid contained within the hydraulic vane cylinder under a resistance by passage of the hydraulic fluid through the one or more hydraulic channels.

A device and method for estimating a resistance of a wheel of a bicycle is disclosed. The device includes a mounting bracket, a disk, and a resistance adjustment knob. The mounting bracket is coupled to the bicycle. The disk is configured to indicate the resistance. The disk is located within the mounting bracket. The resistance adjustment knob is connected to the disk via a connector. Upon rotation of the knob, the connector rotates the disk for estimating the resistance of the wheel of the bicycle. The determined estimated resistance is visible on the disk.

An isometric force resistant exercise tool has a left handle form interfaced to a right handle form over an axle shaft locked to the right handle form, the axle shaft supporting a pressure plate, a compress able spring or set of springs, and a compression adjustment handle threaded onto the axle shaft and abutting the compress able spring or spring set, the pressure plate adjacent in assembly to a friction-resistive material fixed on the left handle form, the left handle form including a piston form interfacing with a ring housing on the right handle form, the piston form adjacent in assembly to a friction-resistive material fixed on the right handle form. Gripping the handle forms and rotating the against force resistance exercises one or more muscle groups.

A portable elliptical exercise apparatus where movement of the right pedal or left pedal defines an ellipse having an ellipse width and ellipse height, where the ellipse height can be incrementally varied according to the pedal surface location of a left foot or right foot on a corresponding left pedal or right pedal.
